Next, find the total head loss of the longest piping loop. Finally, calculate the required pump … WebThe pump is working, but the force of gravity causes the water’s rise in the vertical discharge pipe to stop and the net flow stops. This is known as the “shut-off head”, it’s the amount of head a pump can produce at zero flow. To choose your required pump, you need to know two things: the total head and what flow rate you require. Web24 aug. 2024 · To determine where the pump is operating Fathom will calculate the Total Dynamic Head (TDH), which is based on the static head (another term for elevation head), and the friction head (discussed above) in the system. By calculating the static head difference and the total friction head in the system, the TDH can be predicted. handling difficult people book
